Granted: 1981-05-26
Abstract: ABSTRACT OF THE DISCLOSURE         A control circuit for an electromagnetic cutting apparatus includes auxiliary power impulse systems and auxiliary condensers for accelerating an already moving plunger of the cutting apparatus.  The basic control circuit includes photo-electric sensors for sensing the leading and trailing edges of components.  The sensors are part of an electronic circuit for rapidly charging a coil surrounding a core on the plunger for driving a blade downwardly to cut the tape.  Condensers in the electronic circuit are normally charged and, in response to signals from the photoelectric sensors, instantaneously discharge into the coil to actuate the plunger.  The auxiliary power impulse systems and auxiliary condensers are controlled by timers for discharging the auxiliary condensers into the coil a short time after the condensers of the basic circuit and while the plunger is moving to accelerate the latter.

Abstract: "SPOT PLANTER"                          ABSTRACT    The  spot  planter  includes  a   frame   movable forwardly over the  ground  behind  a  towing  vehicle.   A reciprocating dibble is pivotally mounted on the frame  and reciprocates toward and away  from  the  ground  to  cut  a series of planting pockets in the ground,  and  a  seedling ejector reciprocates with the dibble and  ejects  seedlings into the planting pockets.  A packing wheel is also mounted on the frame and is positioned behind and to  the  side  of the dibble and also moves toward and away from  the  ground to engage the ground adjacent the planting pockets  and  to close  the  planting  pockets  about  the   seedlings.    A passenger compartment is mounted on the frame on the  other side of the dibble from the packing  wheel  and  a  workman repeatedly places a seedling in the  seedling  ejector  and actuates the planting cycle of the  machine. The  annular ground engaging surface of the  packing  wheel  is  concave with the edge away from the dibble being of larger diameter than the closer edge, and the packing wheel rotates  on  an axis which causes the larger portion of the  packing  wheel to sweep  and  compress  the  dirt  adjacent  the  planting pockets laterally toward the planting pockets to close  the planting  pockets  about  the   seedlings   and   to   form depressions  in   the   ground   adjacent   the   seedlings substantially without  reducing  the  height  of  the  soil adjacent the seedlings.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to an apparatus for attaching an electrical contact to the end of an electrical conductor, and more particularly to a semi-automatic device for crimping electrical contacts to electrical conductors.  Prior art semi-automatic crimping devices have been designed to accommodate only a single shape and size of electrical contact.  Due to the large number of different contacts in use, such devices are impractical and uneconomical.  The apparatus of the present invention is embodied in a crimping machine for selectively feeding electrical contacts of any one of a variety of contact conformations seriatim from a supply of the contacts and crimp-ing each contact to the terminal end of an electrical cable or conductor.  The machine includes receptacle means for holding the supply of contacts of selected conformation in an array of loose contacts.  A crimping means, including a crimping station, is provided for crimping at least a portion of a contact onto the electrical conductor when the contact is at the crimping station.  A feeding means selectively feeds a random oriented contact from the receptacle means along a path to the crimping means.  A modular orienting and advancing means is located along the path between the receptacle means and the crimping means for receiving the randomly fed contacts, orienting the contacts and advancing the contacts one at a time toward the crimping means.  Means are provided for selectively changing the modular orienting and advancing means for accommodating the variety of contact configurations.

Abstract: ABSTRACT OF THE DISCLOSURE                      MATTRESS FOUNDATION The present invention relates to bedding mattress foundations for the support of mattresses on bed frames and the like.  Known foam mattresses have been recognized as providing comfort and good support and as not having a tendency of taking a permanent set, thereby allowing the use of such mattress materials on a substantially rigid mattress foundation.  However, the resulting mattress set does not have the give that the purchasing public has come to expect making the mattress set appear to be uncomfortable.  The present invention overcomes this problem by providing an improved foam mattress foundation to provide proper support and to duplicate the feel of box springs.  The mattress foundation utilizes an upper and lower frame assembly separated by a flexible, resilient material, which may be In the form of blocks, strips, or slabs of flexible, resilient material, with the upper frame assembly preferably being somewhat flexible so as to be capable of deforming from Its normal planar condition when subjected to more concentrated loads.  The material separating the upper and lower frame assemblies are selected to have a resilience which will support the weight of one or two persons while distributed over the mattress foundation without substantial deflection, but which will deflect significantly when sub-jected to an individual's weight in more concentrated form, such as occurs when an individual sits on the edge of a bed or is getting into or out of the bed.
